Ask OpenEvidence ↗

OpenEvidence opens in your own logged-in session with the question filled in. Nothing is fetched on your behalf — read it there, then add what you want to teach as a point below, citing the source it came from.

21 candidate papers

Ticked papers are the ones a deck may be built from. Unticking one needs a reason — the citation gate proves a paper exists, and nothing but you decides whether it should be taught. A tier badge appears where the paper’s publication type is known.

Runs the tiered searches, drafts one point per included paper, runs the citation gate and builds a draft deck — the steps below, unattended. Same-day build — drafted locally (medgemma:27b), confirmed against each abstract. The deck still lands in draft: nothing here approves anything.

This meta-analysis found that combining a quadratus lumborum block with a fascia iliaca compartment block ranked highest for reducing total morphine consumption at 24 hours after primary total hip arthroplasty. PMID 40483183 kept
This PROSPECT guideline recommends quadratus lumborum blocks for elective caesarean section under neuraxial anaesthesia if intrathecal opioid was not administered. PMID 33370462 kept
This randomized controlled trial found that for posterior lumbar interbody fusion, quadratus lumborum block at lateral supra-arcuate ligament with 20 mL of 0.4% ropivacaine per side reduced PACU stay by 11 minutes and improved 12 h activity pain scores versus erector spinae plane block. PMID 41168374 kept
This review found that quadratus lumborum blocks offer a promising alternative for post-cesarean delivery analgesia, though no single field block technique has demonstrated clear superiority over the other. PMID 40652293 kept
This meta-analysis found that while quadratus lumborum block statistically reduced 24-hour morphine consumption by 4.61 mg in total laparoscopic hysterectomy patients, this reduction was below the 10 mg minimal clinically important difference and did not decrease postoperative nausea and vomiting. PMID 40154947 kept
This randomized controlled trial found that for laparoscopic cholecystectomy, ultrasound-guided quadratus lumborum plane block provided significantly lower Numerical Rating Scale pain scores up to 24 hours and required less tramadol compared to external oblique intercostal plane block. PMID 41155827 kept
